Forms

Conflict of Interest

All authors must declare any conflicts of interest. When submitting your manuscript via Editorial Manager, you will be asked whether you have any conflicts of interest. As submitting author, it is your responsibility to ascertain any conflicts of interest from your co-authors and to highlight these accordingly. If you are unable to declare any conflicts of interest on behalf of your co-authors, all contributing authors will need to complete and return Conflict of Interest forms. These must be sent to the editorial office by fax to: +44 (0)1865 355906.

Any potential conflict of interest that might constitute an embarrassment to any of the authors if it were not to be declared and were to emerge after publication should be declared. Such conflicts might include, but are not limited to, author (or first degree relative) shareholding in or receipt of a grant or consultancy fee from a company whose product features in the submitted manuscript or which manufactures a competing product.

In addition, all authors must submit a statement of Conflict of Interest to be published at the end of their article. If no Conflict of Interest is declared, this will be stated in the article using the following wording:

'Conflict of interest: none declared'

Submission of manuscripts

EP - Europace operates a web-based system for submission and peer-review, Editorial Manager. This system is intended to reduce manuscript processing times. Text, tables and figures should be prepared in accordance with the instructions given under "Preparation of Manuscripts" below.

Authors must specify the category for which their submission is intended.

If you need help with the electronic submission process please contact the editorial office. Enquiries about the review process and other journal matters should also be directed to the Editorial Office.

Online submission

Please go to the Editorial Manager website for EP - Europace, and follow the instructions given on screen. First-time users must click 'Register' on the navigation menu at the top of the screen, and enter the required information. The system will send you an automatic e-mail with your username and password. Detailed guidelines are available at the Editorial Manager site, by clicking on 'Help' or viewing the author or reviewer tutorials.

You will be asked to supply information about your manuscript and then attach your files containing the text and any figures and tables. Editorial Manager will create a PDF from your data, which is the format in which the manuscript will be made available to the editors and referees during the peer-review process.

The manuscript text, references and figure legends should be prepared in a single file. Papers should be submitted Microsoft Word where possible, although other standard word-processing formats may be acceptable. The manuscript must not be submitted in .pdf format.

Any appendices must be supplied separately, and will be published as online-only supplementary data. Please change any references to Appendices in the manuscript to 'Supplementary', e.g. Supplementary Table S1, Supplementary Appendix 2.

Tables and figures may be included in the manuscript file, but must appear at the end of the text on separate sheets (and not embedded in the text).

If preferred, tables and illustrations may be prepared and submitted in separate files. Electronically submitted figures should be in high resolution and in one of the following formats: tiff, bitmap (.bmp), jpeg (.jpg), postscript (.ps or .eps) or as PowerPoint or Excel files. (Should the manuscript be accepted, the original photographs may be required for use in the production process.) Tables may be submitted as Word tables, or in .rtf format.

You will be required to enter the Abstract, Condensed Abstract, Representative Figure and Keywords during the submission process. These may be copied and pasted from the manuscript document, but must still appear in the manuscript itself. Please supply the names and addresses of three referees to whom your manuscript may be sent for review in the 'Enter Comments' section of your electronic submission.

When completing the 'Add Authors' section, please enter the names of the all the authors listed on the manuscript.

Fast track publication

Ethics

The manuscript should state that the study complies with the Declaration of Helsinki, that the research protocol is approved by the locally appointed ethics committee, and that the informed consent of the subjects (or their parents) has been obtained. Any potential conflict of interest should be declared to the Editor.

Funding

Details of all funding sources for the work in question should be given in a separate section entitled 'Funding'. This should appear before the 'Acknowledgements' section.

The following rules should be followed:

  • The sentence should begin: ‘This work was supported by …’
  • The full official funding agency name should be given, i.e. 'the National Cancer Institute at the National Institutes of Health’ or simply 'National Institutes of Health' not ‘NCI' (one of the 27 subinstitutions) or 'NCI at NIH' (full RIN-approved list of UK funding agencies) Grant numbers should be complete and accurate and provided in brackets as follows: ‘[grant number ABX CDXXXXXX]'
  • Multiple grant numbers should be separated by a comma as follows: ‘[grant numbers ABX CDXXXXXX, EFX GHXXXXXX]’
  • Agencies should be separated by a semi-colon (plus ‘and’ before the last funding agency)
  • Where individuals need to be specified for certain sources of funding the following text should be added after the relevant agency or grant number 'to [author initials]'.

An example is given here: ‘This work was supported by the National Institutes of Health [P50 CA098252 and CA118790 to R.B.S.R.]; and the Alcohol & Education Research Council [hfygr667789].’

Oxford Journals will deposit all NIH-funded articles in PubMed Central. See http://www.oxfordjournals.org/for_authors/repositories.html for details. Authors must ensure that manuscripts are clearly indicated as NIH-funded using the guidelines above.
